Title: Catalyst and process for the production of amines by the catalytic hydrogenation of nitriles
IPC: B01J23/89
Filed: 1968-04-26
Abstract: 1,214,035. Production of amines. CHEMISCHE WERKE HULS A.G. 26 April, 1968 [28 April, 1967], No. 19819/68. Heading C2C. [Also in Division B1] Amines are prepared by the catalytic hydrogenation of the corresponding nitriles in the presence of a cobalt catalyst precipitated on a carrier of coarsely pored α-Al 2 O 3  having a crystalline fraction of α-Al 2 O 3  of more than 70% by weight, a specific surface area of 0À5- 30 sq. m./g. and a water absorption of 30- 60 cc./100 g. The catalyst may contain 5-35% by weight of cobalt and also 0À05-12% by weight of one or more other metals e.g. Cr, Mn, Ni or Ag. The reaction is preferably carried out in the presence of NH 3  and an inert diluent, such as toluene or methanol, at 80-120 C. at superatmospheric pressure. In the examples adiponitrile is converted to hexamethylenediamine using a Co(Mn/Ag catalyst on an α-Al 2 O 3  base and 1,2-bis-(#-cyanoethoxy) ethane is converted to 1,2-bis-(γ-aminopropoxy)ethane using the same catalyst.

Title: Improved method of, and means for, producing knotted pile fabrics
IPC: D03D39/00
Filed: 1944-10-14
Abstract: 618,944. Weaving knotted pile fabrics; beat-up motions; reeds. PICKING, W. T. Oct. 14, 1944, No. 19890. [Classes 142(ii), 142(iii) and 142(iv)] Pile fabrics having Persian knots are woven in a loom, Fig. 3, including a main slay 19 and an auxiliary slay 23 (both opentopped), fixed and moving combs 48, 49. and a reed 39 having flexible dents, Fig. 2. At the beginning of a cycle, Fig. 3, the auxiliary slay 23 beats up the weft 47 (its dents entering the comb 48) and, on encountering the previously inserted pile knots, is given an upward movement to tighten the knots (the front of the dents being serrated for this purpose); the comb 49 has moved out of the way just before the auxiliary slay reaches the fell. Tubes. grippers, or needles introduce pile yarns between pairs of warp yarns, after which the auxiliary slay moves out of the warp and the tubes &c. move the pile yarns forward to the fell. The warp yarns 16, 17 are then lifted out of the main slay 19, the reed 39 is shogged to move them laterally, and the yarns 16 are lowered into dents next to those they occupied originally; the reed is then shogged back two dents of the main slay beyond its original position and the yarns 17 are lowered into the slay, Fig. 9. The main slay then moves forward to the fell, thus crossing each warp yarn 16 with the yarn 17 of an adjacent pair and pressing them round the pile yarns, Fig. 11. The comb 49 then moves rearwardly and upwardly through the comb 48 to tuck the lower ends 51 of the pile yarns through the warp behind the crossings, Fig. 11. When the main slay recedes, the pile yarns (if inserted by tubes or needles) are cut and the auxiliary slay 23 returns to the position shown in Fig. 3. The warp is then lifted out of the main slay 19, whereupon the yarns 16, 17 uncross. thereby transforming the loops of pile yarn into Persion knots, Fig. 18. For the next cycle, the warp yarns 16 and 17 exchange roles, the yarns 16 being lowered for the insertion of weft. Beat-up mottoes.-The auxiliary slay 23 is actuated by a cam 33 which oscillates it about a point 28 on an arm 29, and by a cam 35 which raises and lowers the arm 29 to move the slay into and out of the warp and give it a sharp upward movement to tighten the knob. Reeds.-The reed wires 40 may each comprise a pair of thin flexible strips.

Title: Improvements in and relating to the control of engine-driven electric generating plant
IPC: H02P7/06
Filed: 1945-08-03
Abstract: 596,892. Automatic control systems for generators. ENGLISH ELECTRIC CO., Ltd., and SPAINK, J. H. ABBINK-. Aug. 3, 1945, No. 20009. [Class 38 (iv)] In an automatic speed control arrangement for an engine-driven generator supplying a varying load, e.g. traction motor, the generator excitation is controlled by a switch arranged to open or close in response to deviations of engine speed from a datum and is arranged to be varied gradually in the corrective sense in response to the switch operation. The generator 1 supplying traction motors 2 and 3 has shunt field la and separately excited and mutually assisting fields 1b and 1c connected across the D.C. supply 4. At load currents up to that corresponding to the maximum rated engine output at full fuel supply the governor 7 maintains the switch 6 closed, thus energizing the field 1c and the associated dynamo-electric machine 8. The latter operates as a motor and drives the flywheel 9. With an increase in the load of generator 1 above the maximum the switch 6 is opened by governor 7, consequent upon a fall in engine speed, and the field 1c is disconnected from the source 4 but still energized from machine 8, now operating as a dynamo, at a rate decreasing gradually as the kinetic energy of the flywheel 9 and armature of 8 is absorbed. Conversely should the load in generator 1 now be reduced, the switch 6 will be closed but the excitation of field 1c will rise gradually at a rate depending on the voltage developed across machine 8, now operating again as a motor, which in turn depends on the increase in speed of 8 and thus on the combined inertia of flywheel 9 and armature 8. The governor 7 may be an auxiliary one or may be the main control governor and in a modification, the damping of the rate of change of current in the field winding may alternatively be produced by means of a variable resistor in series, with the field, controlled electrically or hydraulically by the governor. According to the Provisional Specification the governing control is exercised through the field circuit of the generator exciter.

Title: Improvements in power-operated hoists
Inventor: LUNN RICHARD TURNER
IPC: B66D1/14
Filed: 1959-06-11
Abstract: 890,405. Controlling winding gear. A.C.E. MACHINERY Ltd. Sept. 5, 1960 [June 11, 1959], No. 20029/59. Class 78 (5). The invention relates to poweroperated hoists of the kind in which the winding drum is eccentrically mounted so that it can be moved into engagement with a brake by the operation of a control lever 18. According to the invention, the lever 18 is weighted and means are provided responsive to the tension in the hoisting cable 2 and operable to assist the movement of the lever 18 into the operating position. As shown, the lever 18 is movable into operating position by raising an operating handle 13 which acts through the collapsible links 14, 15, and a link 17. The links 14, 15, are held in engagement from collapsing by a spring 16. The hoisting rope 2 passes over a pulley 1, the axis 4 of which is mounted in slots 5 in bearing-plates 6, and carries an arm 7 connected to a bell-crank 8. The other arm of the bellcrank 8 is connected by a cord 10 to the bellcrank 11 carrying the operating handle 13. Thus when the winch is under load, the tension in the hoisting rope 2 causes the axle 4 of the pulley 1 to rise in the slot 5 and thereby rotate the bell-crank 8 and act through the cord 10 to provide a servo action assisting the operating handle 13. The hoisting rope 2 passes to the top (not shown) of a mast 3 and customary trip mechanisms (not shown) are provided at the top and bottom of this mast. The trip mechanisms are operable on respective ends of a rope 19 passing around a pulley 20 carried by the lever 15. A pull on either end of the rope 19 will thus deflect the lever 15 against the spring 16 so as to release the lever 14 and permit the lever 18 to fall into the brake position. In a modification (not shown), the linkage 14, 15, is broken by means of a further spring, the action of which is only inhibited as long as the operating handle 13 is held raised. Specification 576,514 is referred to.

IPC: G05D1/00
Filed: 1958-06-23
Abstract: 897,627. Fluid-pressure servomotor control systems. SPERRY GYROSCOPE CO. June 10, 1959 [June 23, 1958], No. 20054/58. Addition to 828,785. Class 135. Control apparatus for aircraft having a control surface in at least two independently-movable portions 11, 12, each having a main actuator 13, 14 moved in dependence on a signal applied to the associated actuator controlmeans 1, has a first auxiliary actuator 22 for applying a signal from a first automatic pilot 21 to the control means of one main actuator 14, a second auxiliary actuator for applying a signal from a second automatic pilot to the control means of a second main actuator 13, and a connection 5, 27, 19 from the output of the main actuators effective during an automatic mode of operation, i.e. when one automatic pilot is in control, e.g. that in the lower control channel A of the Figure, to apply a signal, corresponding to the signal from the automatic pilot to its associated actuator, to each of the other main actuators, e.g. in upper channel B. With switch 6 moved to cut out the automatic pilots and release the holding means 11, movement of the manual controller 17 actuates both control means 1 via floating lever 19, links 3 and 7, and spring boxes 4, follow-up from the actuator outputs occurring at 5, 27, 19. Should one actuator fail, control passes through the remaining actuator. On moving switch 6 to bring in the automatic pilot in channel A, a solenoid 13 moves a lever 10 to lock a slide 8 carrying the pivot of floating lever 19 to link 3 of actuator 14. The automatic pilot controls surface 12 via auxiliary actuator 22 and main actuator 14, follow-up occurring via potentiometer 15 and, via links 5 and 27, the lever 19 turns on its fixed pivot at 8 to move lever 17 against the artificial feel device 2 and moves the link 3 pivoted to the unlatched upper slide 8 whereby the control surface 11 is correspondingly moved via control means 1 and main actuator 13. The other automatic pilot in channel B acts as a standby pilot which may be used on failure of the automatic pilot in channel A and which monitors the latter pilot via a comparator 16 so that any discrepancy between them actuates a warning or a cut-out. Surfaces other than 11, 12 may be actuated through channels similar to A, B but containing no automatic pilot. They would be operated from the manual controller 17 or via the feedback from the main actuator under automatic pilot control. A number of comparators 16 may compare signals at corresponding positions along the two channels. In another embodiment, the control surface may have more than two movable portions, but only two will have control channels identical with sections A and B, the others having no autopilot 21, auxiliary actuator 22 or differential link 7 and being controlled manually through channels similar to A and B or automatically by movement of the lever 17 resulting from the connected autopilot in channel A or B.

Title: Improvements in machines for rolling screw threads
IPC: B21H3/06
Filed: 1924-08-25
Abstract: 221,210. Scovill Manufacturing Co., (Assignees of Wayne, G. H.). Aug. 30, 1923, [Convention date]. Rolling screw-threads.-In a platen machine for rolling screw-threads, one of the dies has a floating movement transversely of the blank travel to compensate for any slipping of the blank with respect to the dies. The slide 14 is provided with a holder 15 for a die block 16 which is secured by clamps 17 and bolts 18, and is reciprocated by a connecting-rod 20 driven from a pulley 26 through gears 24 and crank disc 21. The complementary die 33 is mounted in a carrier 30 in a stationary adjustable block 28. If slipping of the blank A, Fig. 8, occurs, the thread formed by the die member B will be shifted to some such position as is shown in full lines on the co-operating die C. In order to allow the die-threads (shown dotted) to take up this position and so avoid deformation of the thread, the die 33 is carried in a block 40 which is pivoted at 43 in the holder 30 and has limited pivotal movement between top and oottom ledges 41, 42. The end of the die opposite the pivot bears against a roller 44. At the commencement of the operation on a blank 100, the floating die is held in normal position by a wedge 51 controlled through springs by a rod 55 connected to a lever 67 coacting with a roller 66 adjustably secured to a bracket on the moving die-carrier. On the idle return stroke the roller actuates the lever 67 to pull the rod 55 which draws the wedge into a notch 50 and locks the floating die but at a predetermined point in the operative travel the lever is released to the dotted position in Fig. 4, whereupon a stop 70 on the control rod withdraws the wedge so that the compensating movement about the pivot 43 may occur. For rolling righthand threads the floating movement is in an upward direction, while for left-hand threads it is in a downward direction, movement of the die under gravity being in this case prevented by a spring plunger 72 engaging the bottom ledge of the die-carrier and mounted in a housing in the block 40.

Abstract: 358,485. Sight testing apparatus. WHITEHEAD, F. P., (trading as WHITEHEAD & CO., F.), 34, Pickets Street, Balham, London. July 7, 1930, No. 20493. [Class 97 (i).] In a scotometer or a perimeter in which a colour object is moved across a flat background, or along a circular path, the movements of the colour object are controlled by a wheel situated in front of the main stationary bearing of the instrument. Means may be provided for operating the wheel from a distant position. A hollow spindle D passing through the main stationary bearing C carries at its rear end a bar D3 in which is slidably mounted a rack D4 carrying the recording point D5, and at its front end a bar E in which is mounted a rack E1 carrying the colour object E3. The colour object and recording point can thus be rotated together about the axis of the bearing C. A notched plate D2 secured to the spindle D co-operates with a detent F2 to enable the rotation to be arrested in given meridians. The record surface is carried by a frame G hinged at Gl to a member G2 supported by the tube A, the frame being held vertically between a spring-urged disc H4 and a turn-button H5. The record surface can be moved into contact with the point D5 by Bowden &c. mechanism fitted in the threaded aperture H8. To enable the object E3 and point D5 to be moved simultaneously and proportionately towards, or away from, the axis of the bearing C, a spindle J passing through the spindle D carries at one end a pinion Jl gearing with the rack D4 and at the other end a gear wheel J3 meshing with a pinion J4 which operates the rack E1. The pinion J4 is fast with a pinion K2 gearing with the controlling wheel K which may be provided with handles K3. To enable the control to be effected from a distance, a bevel wheel K1 is mounted with the wheel K and gears with a bevel wheel K4 to which is secured a long rod K7 provided at its outer end with an operating knob or handle.

IPC: C10G55/04
Filed: 1956-07-03
Abstract: A hydrocarbon fraction preferably boiling in the range 200-600 DEG F. containing alkyl substituted aromatic hydrocarbons is treated to obtain a product containing an aromatic hydrocarbon having a lesser number of carbon atoms than the alkyl substituted aromatic hydrocarbon by the following steps: (1) solvent extracting the hydrocarbon fraction to obtain a substituted aromatic hydrocarbon fraction preferably boiling in the range 200-600 DEG  F.; (2) fractionating this fraction in the absence of oxygen to obtain a distillate free of metallic compounds and peroxides; (3) storing under a blanket of an inert gas; (4) dealkylating in the absence of oxygen and active catalyst at 1100-1800 DEG  F., at least 400 p.s.i.g., in the presence of at least one molecule of hydrogen per alkyl group in the hydrocarbon for at least one second.  The solvent extraction step may be carried out with phenol or sulphur dioxide. An example is given showing that deposits in the dealkylation reactor are less than in a method where metallic and peroxide compounds are not excluded.
